Host wrote intent to cancel 30-night stay by Airbnb e-mail 20 hours before scheduled check-in. Then, never canceled the booking - creating significant difficulty, the necessity to double book, and spend much time and effort finding alternative accommodations, in phone and e-mail communication with Airbnb, and my credit card company. As a matter of fact, I received the informal cancellation note while checking in for the flights to Thailand and never heard from the Host again?
